Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for managing power usage of one or more devices, the method comprising: responsive to a first input received at a first input device, a first amount of power supplied from a power supply to a processor and power supplied from the power supply to a display device, a second input device and a communication unit in a ready state, transitioning from an off state where the power supply does not supply power to the display device, the communication unit, the second input device and the processor to the ready state, wherein the communication unit comprises a plurality of transceivers including a wireless transceiver; transitioning from the ready state to a dozing state responsive to the second input device and the display device not receiving a second input for a predetermined length of time, ceasing to supply power from the power supply to the communication unit in the dozing state and decreasing, but not ceasing, power supplied to the processor in the dozing state; operating in a wait state by supplying power to the display device, the second input device and the processor while providing a low amount of power from the power supply to a first transceiver included in the communication unit and not supplying power to a second transceiver included in the communication unit; and responsive to receiving a third input to access an inbox or to submit a document while operating in the wait state, operating in a first transceiver test state by providing the low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver.
A method for power management in a portable device involves transitioning between power states based on user input and device activity. Initially, the device is off (no power to display, communication unit, input, or processor). A user input turns it to a ready state, powering up the processor, display, input, and a communication unit containing multiple transceivers. If there is no input, the device transitions to a dozing state, cutting power to the communication unit but reducing (not cutting off) power to the processor. A "wait" state powers the display, input, and processor and provides low power to a first transceiver but no power to a second. If an input triggers accessing an inbox, the device switches to a first transceiver test state, maintaining low power to the first transceiver and no power to the second.
2. The method of claim 1 , further comprising: transitioning from the ready state to an active state responsive to determining that a memory includes data for display using the display device, writing the data for display to the display device and increasing the power supplied to the processor from the first amount to a second amount in the active state; transitioning from the ready state to the off state responsive to the first input device receiving a first type of input; transitioning from the ready state to a sleep state responsive to the first input device receiving a second type of input, ceasing to supply power from the power supply to the display device, the communication unit and the second input device and decreasing power supplied to the processor in the sleep state; transitioning from the active state to the off state responsive to the first input device receiving the first type of input while in the active state; transitioning from the active state to the sleep state responsive to the first input device receiving the second type of input while in the active state; and transitioning from the active state to the ready state responsive to determining that there is no data to display using the display device.
The power management method described previously (powering devices based on inputs and lack of activity) includes additional state transitions. When data is available for display, the device goes from "ready" to "active," increasing processor power. A specific input type can force transitions from "ready" to "off" or from "ready" to "sleep," where display and communication are powered off, and the processor's power is reduced. The same input type can transition the system from "active" to "off" or "active" to "sleep." Finally, the system transitions from "active" to "ready" when no display data is available.
3. The method of claim 2 , further comprising: transitioning from the dozing state to the ready state responsive to the second input device receiving the second input while in the dozing state; transitioning from the dozing state to the sleep state responsive to the first input device receiving the second type of input while in the dozing state, ceasing to supply power from the power supply to the display device, the communication unit and the second input device and decreasing power supplied to the processor in the sleep state; and transitioning from the dozing state to the off state responsive to the first input device receiving the first type of input while in the dozing state.
The power management method described previously (powering devices based on inputs and lack of activity, and transitioning between ready, active, off and sleep states) also transitions between dozing, sleep and off states. Receiving user input on the second input device while dozing returns the device to the ready state. Receiving a specific input type while dozing transitions the device to sleep mode, cutting power to the display, communication unit and the second input device while decreasing power to the processor. Receiving a different input type when dozing transitions the device to the off state.
4. The method of claim 3 , further comprising: transitioning from the sleep state to the off state responsive to the first input device receiving the first type of input while in the sleep state; and transitioning from the sleep state to the ready state responsive to the first input device receiving the second type of input while in the sleep state.
The power management method described previously (powering devices based on inputs and lack of activity, and transitioning between ready, active, off, sleep and dozing states) defines transitions within sleep mode. A specific input type when the device is in sleep mode transitions it to the off state. A different input type while in sleep transitions it to the ready state.
5. The method of claim 1 , further comprising: operating in an asleep/off communication state where power is not supplied from the power supply to the display device, the second input device, the processor, the first transceiver and to the second transceiver; responsive to receiving a fourth input, determining whether to operate in an airplane state; responsive to determining to operate in the airplane state, operating in the airplane state by supplying power to the display device, the second input device and the processor while not supplying power to the first transceiver and to the second transceiver; and responsive to determining not to operate in the airplane state, operating in the wait state by supplying power to the display device, the second input device and the processor while providing the low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver.
The power management method (powering devices based on inputs and lack of activity and including transitions between various states) has an "asleep/off communication" state (no power to display, input, processor, or transceivers). A user input triggers a check for airplane mode. If airplane mode is enabled, power is supplied to the display, input, and processor, while both transceivers are off. If airplane mode is not enabled, the system enters the wait state, where the display, input, and processor are powered, a first transceiver has low power, and a second transceiver is off.
6. The method of claim 5 , further comprising: responsive to a location services trigger while operating in the wait state, operating in a second transceiver locate state by ceasing power supplied from the power supply to the first transceiver and supplying power to the second transceiver; and responsive to receiving location information via the second transceiver, operating in the wait state by ceasing power supplied from the power supply to the second transceiver and providing the low amount of power from the power supply to the first transceiver.
The method from the previous description (powering devices based on inputs and lack of activity, transitioning between states, and including airplane mode logic) enables the location services to manage power. While in the "wait" state (display, input, and processor are powered, first transceiver has low power, and a second transceiver is off), a location services trigger activates a "second transceiver locate" state where the first transceiver is off, and the second transceiver is powered on. When location data is received, the system returns to the "wait" state, turning off the second transceiver and providing low power to the first transceiver.
7. The method of claim 5 , further comprising: while in the first transceiver test state, determining whether a first network is accessible to the first transceiver; responsive to determining that the first network is accessible to the first transceiver, operating in a first transceiver synchronization state by increasing the power from the power supply to the first transceiver and transmitting data to the first network using the first transceiver; responsive to completing transmitting the data to the first network using the first transceiver, operating in the wait state by reducing power supplied from the power supply to the first transceiver to the low amount of power while not supplying power to the second transceiver; responsive to determining that the first network is inaccessible to the first transceiver, determining whether the second transceiver is enabled; responsive to determining that the second transceiver is enabled, operating in a second transceiver synchronization state by ceasing power supplied from the power supply to the first transceiver, and supplying power from the power supply to the second transceiver; transmitting the data to a second network using the second transceiver; and responsive to completing transmitting the data to the second network using the second transceiver, operating in the wait state by ceasing power supplied from the power supply to the second transceiver and providing the low amount of power from the power supply to the first transceiver.
The power management method described previously (powering devices based on inputs and lack of activity and including airplane mode logic) includes network synchronization. While in the first transceiver test state (display, input, and processor are powered, first transceiver has low power, and a second transceiver is off) the system checks if a first network is available to the first transceiver. If so, it goes to a "first transceiver synchronization" state, increasing the first transceiver's power to transmit data. After transmission, it returns to the wait state (first transceiver at low power, second transceiver off). If the first network is unavailable, the system checks if the second transceiver is enabled. If so, it enters a "second transceiver synchronization" state (first transceiver off, second transceiver powered) to transmit data via a second network before returning to the wait state (second transceiver off, first transceiver at low power).
8. A method for managing power usage of one or more devices, the method comprising: operating in an asleep/off communication state where power is not supplied from a power supply to a display device, a processor, a first transceiver and a second transceiver; responsive to receiving a first input, operating in a wait state by supplying power to the display device and the processor while providing a low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver; responsive to receiving a second input to access an inbox or to submit a document while operating in the wait state, operating in a first transceiver test state by providing the low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver; responsive to a location services trigger while operating in the wait state, operating in a second transceiver locate state by ceasing power supplied from the power supply to the first transceiver and supplying power to the second transceiver; and responsive to the second transceiver receiving location information, operating in the wait state by ceasing power supplied from the power supply to the second transceiver and providing the low amount of power from the power supply to the first transceiver.
A method for managing power usage involves a power supply, display device, processor, and two transceivers. The system starts in an "asleep/off communication state" with no power to the components. Receiving a first input transitions it to a "wait state," supplying power to the display and processor while providing low power to the first transceiver and not supplying power to the second transceiver. Receiving a second input to access an inbox or submit a document transitions it to a "first transceiver test state," providing low power to the first transceiver and not supplying power to the second transceiver. A location services trigger moves it to a "second transceiver locate state" with the first transceiver off and the second on. Receiving location information returns the system to the "wait state," turning off the second transceiver and giving low power to the first.
9. The method of claim 8 , wherein operating in the wait state comprises: determining whether to operate in an airplane state; responsive to determining to operate in the airplane state, operating in the airplane state by supplying power to the display device and the processor while not supplying power to the first transceiver and to the second transceiver; and responsive to determining not to operate in the airplane state, operating in the wait state.
The power management method from the previous description (powering devices based on inputs and location service triggers) includes airplane mode logic. In the "wait state" (display and processor powered, first transceiver at low power, second transceiver off), the system checks if airplane mode is enabled. If so, it enters airplane mode, powering the display and processor but turning off both transceivers. If airplane mode is not enabled, the system remains in the wait state.
10. The method of claim 8 , wherein the location services trigger is a request for location identification.
The power management method from the previous description (powering devices based on inputs and location service triggers, including airplane mode logic) specifies the location services trigger as a request for location identification.
11. The method of claim 8 , wherein operating in the first transceiver test state further comprises: determining whether a first network is accessible to the first transceiver; responsive to determining that the first network is accessible to the first transceiver, operating in a first transceiver synchronization state by increasing the power from the power supply to the first transceiver; transmitting data to the first network using the first transceiver; and responsive to completing transmitting the data to the first network using the first transceiver, operating in the wait state by reducing power supplied from the power supply to the first transceiver to the low amount of power while not supplying power to the second transceiver.
The power management method (powering devices based on inputs and location service triggers, including airplane mode logic) includes network synchronization logic. While in the "first transceiver test state" (first transceiver at low power, second transceiver off), the system determines if a first network is accessible to the first transceiver. If the first network is accessible, the system transitions to a "first transceiver synchronization state," increasing the power to the first transceiver, transmitting data, and returning to the wait state by reducing the first transceiver's power and not powering the second transceiver.
12. The method of claim 11 , further comprising: responsive to determining that the first network is inaccessible to the first transceiver, determining whether the second transceiver is enabled; responsive to determining that the second transceiver is enabled, operating in a second transceiver synchronization state by ceasing power supplied from the power supply to the first transceiver and supplying power from the power supply to the second transceiver; transmitting the data to a second network using the second transceiver; and responsive to completing transmitting the data to the second network using the second transceiver, operating in the wait state by ceasing power supplied from the power supply to the second transceiver and providing the low amount of power from the power supply to the first transceiver.
The power management method described previously (powering devices based on inputs and location service triggers, including airplane mode logic and network synchronization) includes further network selection. If the first network is inaccessible (when in the first transceiver test state, with first transceiver at low power and second off), the system checks if the second transceiver is enabled. If so, it enters a "second transceiver synchronization state" (first transceiver off, second transceiver powered) to transmit data via a second network before returning to the wait state (second transceiver off, first transceiver at low power).
13. The method of claim 8 , further comprising: responsive to a third input received at a first input device, a first amount of power supplied from the power supply to the processor and power supplied from the power supply to the display device and to a second input device in a ready state, transitioning from an off state where the power supply does not supply power to the display device, the second input device and the processor to the ready state; transitioning from the ready state to an active state responsive to determining that a memory includes data for display using the display device, writing the data for display to the display device and increasing the power supplied to the processor from the first amount to a second amount in the active state; transitioning from the ready state to the off state responsive to the first input device receiving a first type of input; transitioning from the ready state to a sleep state responsive to the first input device receiving a second type of input, the power supply ceasing to supply power to the display device and the second input device while decreasing power supplied to the processor in the sleep state; and transitioning from the ready state to a dozing state responsive to the second input device and the display device not receiving a fourth input for a predetermined length of time, the power supply ceasing to supply power to the first transceiver and the second transceiver while decreasing power supplied to the processor in the dozing state.
The power management method (powering devices based on inputs and location service triggers, including airplane mode logic, network selection) includes state transitions based on different user inputs. A third user input moves the device from "off" to "ready," powering the processor, display, and input. If data is available, the device goes to "active," increasing processor power. An input transitions the device to "off" or "sleep," where display and input are off, and the processor power is decreased. A period of inactivity leads to the "dozing" state, where transceivers are off, and processor power is decreased.
14. The method of claim 13 , further comprising: transitioning from the dozing state to the ready state responsive to the second input device receiving the fourth input while in the dozing state; transitioning from the dozing state to the sleep state responsive to the first input device receiving the second type of input while in the dozing state; transitioning from the dozing state to the off state responsive to the first input device receiving the first type of input while in the dozing state; transitioning from the sleep state to the off state responsive to the first input device receiving the first type of input while in the sleep state; transitioning from the sleep state to the ready state responsive to the first input device receiving the second type of input while in the sleep state; transitioning from the active state to the off state responsive to the first input device receiving the first type of input while in the active state; transitioning from the active state to the sleep state responsive to the first input device receiving the second type of input while in the active state; and transitioning from the active state to the ready state responsive to determining that there is no data to display using the display device.
The power management method described previously (powering devices based on inputs and location service triggers, including airplane mode logic, network selection, and transitions based on user input) includes further state transitions. Receiving user input when dozing returns the device to the ready state. Receiving a specific input type when dozing transitions the device to sleep or off. Specific input types when sleep transitions it to off or ready. The same input type can transition the system from active to off or active to sleep. The system transitions from active to ready when no display data is available.
15. A system for managing power usage of one or more devices, the system comprising: one or more processors, the processors being configured to: responsive to a first input received at a first input device, a first amount of power supplied from a power supply to a processor and power supplied from the power supply to a display device, a second input device and a communication unit in a ready state, transition from an off state where the power supply does not supply power to the display device, the communication unit, the second input device and the processor to the ready state, wherein the communication unit comprises a plurality of transceivers including a wireless transceiver; transition from the ready state to a dozing state responsive to the second input device and the display device not receiving a second input for a predetermined length of time, ceasing to supply power from the power supply to the communication unit in the dozing state and decreasing, but not ceasing power supplied to the processor in the dozing state; operate in a wait state by supplying power to the display device, the second input device and the processor while providing a low amount of power from the power supply to a first transceiver included in the communication unit and not supplying power to a second transceiver included in the communication unit; and responsive to receiving a third input to access an inbox or to submit a document while operating in the wait state, operate in a first transceiver test state by providing the low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver.
A system for managing power includes processors configured to transition between states based on input and device activity. Initially, the device is off. An input transitions it to a "ready state," powering the processor, display, input, and a communication unit containing multiple transceivers. Inactivity causes the device to transition to a "dozing state," cutting power to the communication unit but reducing power to the processor. A "wait" state powers the display, input, and processor and provides low power to a first transceiver but no power to a second. If a third input triggers accessing an inbox, the device switches to a "first transceiver test state," maintaining low power to the first transceiver and no power to the second.
16. The system of claim 15 , wherein the one or more processors are further configured to: transition from the ready state to an active state responsive to determining that a memory includes data for display using the display device, writing the data for display to the display device and increasing the power supplied to the processor from the first amount to a second amount in the active state; transition from the ready state to the off state responsive to the first input device receiving a first type of input; transition from the ready state to a sleep state responsive to the first input device receiving a second type of input, ceasing to supply power from the power supply to the display device, the communication unit and the second input device and decreasing power supplied to the processor in the sleep state; transition from the active state to the off state responsive to the first input device receiving the first type of input while in the active state; transition from the active state to the sleep state responsive to the first input device receiving the second type of input while in the active state; and transition from the active state to the ready state responsive to determining that there is no data to display using the display device.
The power management system described previously (transitions between states based on input and device activity) also transitions between ready, active, off and sleep states. When data is available for display, the device goes from "ready" to "active," increasing processor power. A specific input type can force transitions from "ready" to "off" or from "ready" to "sleep," where display and communication are powered off, and the processor's power is reduced. The same input type can transition the system from "active" to "off" or "active" to "sleep." Finally, the system transitions from "active" to "ready" when no display data is available.
17. The system of claim 16 , wherein the one or more processors are further configured to: transition from the dozing state to the ready state responsive to the second input device receiving the second input while in the dozing state; transition from the dozing state to the sleep state responsive to the first input device receiving the second type of input while in the dozing state, ceasing to supply power from the power supply to the display device, the communication unit and the second input device and decreasing power supplied to the processor in the sleep state; and transition from the dozing state to the off state responsive to the first input device receiving the first type of input while in the dozing state.
The power management system described previously (transitions between states based on input and device activity, and transitions between ready, active, off and sleep states) also transitions between dozing, sleep and off states. Receiving user input on the second input device while dozing returns the device to the ready state. Receiving a specific input type while dozing transitions the device to sleep mode, cutting power to the display, communication unit and the second input device while decreasing power to the processor. Receiving a different input type when dozing transitions the device to the off state.
18. The system of claim 17 , wherein the one or more processors are further configured to: transition from the sleep state to the off state responsive to the first input device receiving the first type of input while in the sleep state; and transition from the sleep state to the ready state responsive to the first input device receiving the second type of input while in the sleep state.
The power management system described previously (transitions between states based on input and device activity, and transitions between ready, active, off, sleep and dozing states) defines transitions within sleep mode. A specific input type when the device is in sleep mode transitions it to the off state. A different input type while in sleep transitions it to the ready state.
19. The system of claim 15 , wherein the one or more processors are further configured to: operate in an asleep/off communication state where power is not supplied from the power supply to the display device, the second input device, the processor, the first transceiver and to the second transceiver; responsive to receiving a fourth input, determine whether to operate in an airplane state; responsive to determining to operate in the airplane state, operate in the airplane state by supplying power to the display device, the second input device and the processor while not supplying power to the first transceiver and to the second transceiver; and responsive to determining not to operate in the airplane state, operate in the wait state by supplying power to the display device, the second input device and the processor while providing the low amount of power from the power supply to the first transceiver and not supplying power to the second transceiver.
The power management system (transitions between states based on input and device activity and including transitions between various states) has an "asleep/off communication" state (no power to display, input, processor, or transceivers). A user input triggers a check for airplane mode. If airplane mode is enabled, power is supplied to the display, input, and processor, while both transceivers are off. If airplane mode is not enabled, the system enters the wait state, where the display, input, and processor are powered, a first transceiver has low power, and a second transceiver is off.
20. The system of claim 19 , wherein the one or more processors are further configured to: responsive to a location services trigger while operating in the wait state, operate in a second transceiver locate state by ceasing power supplied from the power supply to the first transceiver and supplying power to the second transceiver; and responsive to receiving location information via the second transceiver, operate in the wait state by ceasing power supplied from the power supply to the second transceiver and providing the low amount of power from the power supply to the first transceiver.
A system for managing power consumption in a device with multiple transceivers addresses the challenge of balancing power efficiency with location tracking functionality. The system includes a power supply, a first transceiver, and a second transceiver. The first transceiver operates in a low-power wait state, consuming minimal power while monitoring for a location services trigger. When such a trigger occurs, the system transitions to a second transceiver locate state, where power is redirected from the first transceiver to the second transceiver. The second transceiver then receives location information, such as GPS signals, while the first transceiver remains inactive. After obtaining the location data, the system returns to the wait state, powering down the second transceiver and restoring minimal power to the first transceiver. This approach ensures that the device conserves energy by activating only the necessary transceiver for location tracking, reducing overall power consumption while maintaining accurate positioning capabilities. The system dynamically adjusts power distribution between transceivers based on operational needs, optimizing efficiency without compromising functionality.
